The Lowdown
Right then, let's have a look at what's cookin' for Jaconé. It’s a bit of a slow starter, but there are a couple of windows that’ll get the stoke up.
We’re looking at an exposed S to SE facing beach break, and it’s an intermediate-level spot. The water is sittin' around 73°, which is pretty much what you’d expect for this time of year – nothing weird going on there.
Alright, the first few days are a bit of a write-off. Sunday afternoon (16th) is a washout with a stiff 22 mph cross-off breeze making a mess of a 4ft S swell. Monday (17th) morning is the first glimmer of hope with a 3ft S groundswell (11-second period) and a clean offshore breeze, giving us moderate wave energy. That's a solid little session for the early birds. Tuesday (18th) morning keeps the clean theme with a gentler offshore and a 4ft E swell, but the period drops to 7 seconds so it’ll be a bit weaker.
Wednesday and Thursday (19th-20th) are pretty ordinary. Tiny waves – under 3 feet – and weak energy. You could get a few but it’s not going to light your fire.
Now, here's the first real standout. Friday morning, the 21st of August. We’ve got a 6ft swell from the ENE with a 8-second period, and the energy is pumping. The wind is a light cross-off breeze, so it should be clean. That’s a fun size, not too big, not too small. It gets a bit lumpy in the arvo when the wind swings onshore, so get on it early. Crowds are a possibility here, so keep an eye out.
Saturday the 22nd starts off glassy with a 4ft SSW swell, but the real deal kicks off on Sunday morning, the 23rd. We have a 6ft SSW groundswell with an 11-second period and a clean cross-off wind. That's a proper, punchy 6ft with good energy. That’s your second standout. It’s got that longer period which means better shaped waves and easier paddling.
Things get a bit more serious and expert-only from the 25th. Tuesday morning (25th) the swell jumps to a solid 10ft from the SSW with a very long 13-second period. The energy is massive. The wind is light and cross-off, but at that size, it’s for experienced chargers only. Tuesday afternoon looks slightly better at 8ft with glassy conditions – a proper big-wave window for those who know what they’re doing.
After that, the swell drops back down through the week, with onshore winds and rain making conditions pretty average through to the 27th. We get another little clean window on Saturday morning, the 29th, with a 5ft ENE swell and a gentle offshore. It’s not huge, but it’s clean and rideable.
The last couple of days of August and into the 31st fizzle out to tiny, weak and choppy conditions.
So, to sum it up: Friday morning the 21st and Sunday morning the 23rd are your best bets for the overall mix of size, clean conditions and good energy. The 25th is for the big-wave crew only.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
